In addition, __3__made to the construction codes in Los Angeles during the last 20 years havestrengthened the city’s buildings and highways, making them more __4__ toquakes.
In the past,making structures quake-resist-ant meant firm yet __5__ materials, such assteel and wood, that bend without breaking. Later, people tried to lift abuilding off its foundation, and insert rubber and steel between the buildingand its foundation to __6__ the impact of ground vibrations. The most __7__designs give buildings brains as well as concrete and steel supports, calledsmart buildings, the structures respond like living organisms to anearthquake’s vibrations. When ground shakes and the building tips forward, thecomputer would __8__ the building to shift in the opposite direction. The newdesigns should offer even greater __9__ to cities where earthquakes ofen takeplace.
The new smart structures could be very __10__ to build. However, they would save manylives and would be less likely to be damaged during earthquakes.
